Children should be supervised to ensure that they do not play with the product.
2.0 INSTALLATION
WARNING – The fan must be isolated from the power supply during installation and
maintenance. The fan must be earthed in accordance with the local regulations.
2.1 Upon receipt, the fan equipment should be visually inspected to check for any damage. Ensure that
the impeller is free to rotate.
2.2 If there are any queries concerning the fan equipment, Elta Fans Ltd should be contacted prior to
the installation.
2.3 The fan must be securely mounted in the desired position to suit the application. The fan can be
mounted on flat or inclined roofs with a maximum pitch angle of 35o.
2.4 Assembly: SSMF fans are supplied with the fan/motor fully assembled to the base/cowl.
DO NOT OVERTIGHTEN THE BOLTS AS THIS MAY DAMAGE THE BASE.
2.5 Backdraught shutters: Backdraught shutters for SSMF fans are supplied as an assembled unit
and are fitted prior to roof unit installation. The shutter assembly top flange locates onto the curb or
purlin box top face.
2.6 Having fitted the shutter tray, it is necessary to make the connections to the motor terminal box
before fitting the roof unit to the curb or purlin box. Feed the supply cable through the grommet hole
in the bottom flange of the shutter tray and make the connections to the terminal box which is
attached to the motor plate.
2.7 Curb mounting: Position the assembled roof unit onto the curb and secure to the timber sill with
M10 coach bolts (not supplied by Elta Fans), ensuring that fibre washers are positioned under each
bolt head. It is advisable to drill pilot holes prior to fitting the bolts to prevent splitting the timber
curb.
DO NOT OVERTIGHTEN THE BOLTS AS THIS MAY DAMAGE THE BASE.
2.8 Purlin mounting:
•Purlin trimmers: - should be bolted to the vertical flange of the purlin member taking
care to align with the roof opening.
•Purlin box: - position onto trimmers and fit M10 type ‘A’ short tail lindaptors (not
supplied by Elta Fans) into holes in the bottom flanges. Do not tighten nuts at this
stage.
•Soaker sheets: - slip the soaker sheet over the purlin box and fix and seal to the roof
sheeting. Align the purlin box with the soaker sheet and tighten the lindaptor nuts.
•Position the roof unit into the purlin box and insert M10 bolts into the four corner holes
and into the purlin box captive fixings ensuring that fibre washers are positioned under
the bolt heads.
DO NOT OVERTIGHTEN THE BOLTS AS THIS MAY DAMAGE THE BASE.
2.9 Check the details on the motor rating plate to ensure that the correct power supply (voltage,
frequency and phase) is available.
An incorrect power supply will lead to permanent damage to the fan motor.
2.10 Refer to the appropriate wiring diagram. Ensure that all earth connections are made.
2.11 Means for electrical disconnection must be incorporated in the wiring installation in accordance with
the relevant wiring and electrical regulations.
2.12 Precaution must be taken to locate the exhaust discharge terminal so as to avoid the backflow of
gases into the room from the open flue of gas or other fuel burning appliances.

3.0 START-UP
3.1 Before power is supplied to the unit, check that the wiring is correct as per the fan connection
diagram.
3.2 At initial start-up, check that impeller rotation and airflow direction is correct.
3.3 Check that the motor amperage draw does not exceed the nameplate rating.
4.0 FAN MAINTENANCE
4.1 Inspection of the fan at least once every 12 months is recommended to ensure that the motor, fan
blades, and supporting guards, are clean. Any build up of dust and deposits on the blades or
guards should be removed using a non-abrasive cleaner.
4.2 All fastenings should be checked for tightness. In addition, all rotating items should be checked.
4.3 Bearings are of the ‘sealed for life’ type and will not need a detailed inspection.
WARNING – This fan is fitted with an auto-reset thermal contact which switches the fan off in the
event of a fault condition.
Once the motor cools down the fan may start unexpectedly.
Only a suitably qualified and competent person may carry out maintenance after the electrical
supply has been isolated.
